The NAND Flash boot also supports all the SLC large block NAND Flash devices.

10.4.3.2 SD Card Boot

The SD Card bootloader uses MCI0. It uses only one valid code detection. It searches a boot.bin file.

Supported SD Card devices

SD Card Boot supports all SD Card memories compliant with SD Memory Card Specification V2.0. This includes

SDHC cards.

10.4.3.3 SPI Flash Boot

Two kinds of SPI Flash are supported: SPI Serial Flash and SPI DataFlash.

The SPI Flash bootloader tries to boot on SPI0 Chip Select 0, first looking for SPI Serial flash, and then for SPI

DataFlash.
